cs_mipi_i2c.sh 参数配置脚本使用说明
1 介绍
cs_mipi_i2c.sh 脚本为通过I2C协议对CS-MIPI-X系列的摄像头进行配置的工具集。
目录下总共4个文件，camera_i2c_config、i2c_read、i2c_write、cs_mipi_i2c.sh。
2 树莓派配置管脚，非树莓派忽略此步
你需要先运行
./enable_i2c_vc.sh
./camera_i2c_config
配置管脚，然后执行cs_mipi_i2c.sh
2.1 camera_i2c_config 使用说明
连接树莓派Computer Module情况下，运行
./camera_i2c_config [cameranum]
| cameranum | description |
|---|---|
| 0 | CAM0 |
| 1 | CAM1 |
连接树莓派经典版型情况下，直接运行
./camera_i2c_config
3 cs_mipi_i2c.sh 使用说明
./cs_mipi_i2c.sh
this shell scripts should be used for CS-MIPI-IMX307!
Usage: ./cs_mipi_i2c.sh [-r/w] [-f] function name -p1 param1 -p2 param2 -p3 param3 -b bus
options:
-r read
-w write
-f [function name] function name
-p1 [param1] param1 of each function
-p2 [param1] param2 of each function
-p3 [param1] param3 of each function
-b [i2c bus num] i2c bus number
-d [i2c addr] i2c addr if not default 0x3b
support functions: devid,hdver,camcap,firmwarever,productmodel,videofmtcap,videofmt,ispcap,i2caddr,streammode,powerhz,sysreset,paramsave
对于树莓派Pi3B / Pi3B+ / 3A / 4B(1G/2G/4G)，使用i2c0, 对于Compute Module/ CM3，使用i2c1,请添加-b1 选项。
